#47 of 100 check engine light by bulldogg Mar 02, 2008 (5:52 am)
i own a 2007 chevy cobalt, first time the check engine light came on it was a fuel injector, the dealer replaced it. the car had 12,0000 miles on it. the light came on again this friday, now the light went off. Does the engine light have to be on for the dealer to find the problem? the car has the same problems hesitation, rough idle. Replies to this message: grosloup (Mar 02, 2008 10:50 am)

Replying to: bulldogg (Mar 02, 2008 5:52 am) No, the engine light doesn't have to be on to find a problem. A similar thing happened with my vehicule.The "theft alarm system light" came on and when a went to the dealer the light was off. They simply plugged a machine under the dash and they had a numeral code that told them exactly what the problem was even if the light wasn't on.

Replying to: prnta (Dec 24, 2007 9:05 pm) Dear cobalt 06, I am experiencing problems with my Cobalt as well. My biggest issue is the security lock flashing on my console when I go to start it in the morning. If I wait half an hour an try again it will usually start and then there are no problems until the next time. I've had it into the dealer 3x's with this issue but it starts for them and then they can't log an error code to identify the problem. My warranty is up, I'm tired of paying the dealer for nothing and nobody can figure this out. I've read through this forum and can't find any solutions. If there is anyone that can help me I'd really appreciate it. Other than that I love this car and thankfully haven't had any of the other problems some people on here have identified. This is a great forum. Thanks for any help you can give me.

I have had my 06 Cobalt at the dealer 6 times in past 6 months with electrical issues from CD playing replaced twice, key stuck in ignition, but biggest safety issue was the 3 times my car died on a highway here in PA. I had all my documentation, letters to GM, owner to dealer, emails. My problems started at 17K. I was so stressed and fed up I contacted our state's Lemon Law. In PA, the Lemon Law is 1 yr/12K but since my problems were recorded at 17K, I was able to get some free help. If you have the Lemon Law available to you, I know my attorney helps NJ, MD, and PA, please try to get some help. I thought it was a total loss for me since I was ready to trade in the lemon and take another big loss. GM offered my free oil changes and tire rotations for 1 yr, BIG DEAL the car didn't run! I was so disgusted, I emailed the Lemon Law in my state and after a few weeks I did get some help.I received money for a down payment on a new vehicle and my attorney fees were paid by GM. GM did refuse to buy my lemon back of course, why should a big corporation take such a big loss. I could have lost my life. After the 3rd time my car completed died on an icy hill in Dec. I decided I couldn't drive it 50 miles a day anymore. Luckily, I proved my case and GM settled. I hope that everyone with 05 and 06 Cobalts can keep calling GM 866.697.7482 or www.gm.com. These cars should have been recalled. GM settled 3 weeks after my Lemon Law claim. Obviously, GM knew there is a problem. I appreciate all the feedback on this website also. The service manager was so rotten to me, I wouldn't buy a piece of gum from him. I always told the company line, "We never have trouble with cobalts", I guess my cobalt broke the mold here in Pittsburgh. I enjoyed the car, even purchased the extended warranty but the car never made it past 21K with me. Pretty pathetic for GM. Never again......

Replying to: charly2 (Feb 22, 2008 9:19 pm) hey charly . . .   i have a 2005 cobalt and i may have the same problem . . . .   recently (2 months ago) i noticed that oen of my headlights didnt work when i unlocked it with my remote. so i figured i need a new bulb . . then it came back on so i forgot about it.   NOW when i hit my unlock on the remote BOTh low beams come on . .like theyre supposed to . . but when i put my key int he on position and go to start my car they both go off. High beams both work . . . but not the low beams . . . i can go up and hit the driverside headlamp and it will comeon but it wont work for the other low beam.   it happens more consistantly now than before so .. . im also curious how to fix it because i dont think a bulb replacement will do since they both work . . .   if you hear anything let me know   joseph

#54 of 100 05 and 06 Cobalts had many issues by gerald41 Mar 17, 2008 (9:33 am)
I had an 06 before it was recently totaled. I use to chat with the srvice manager while waiting for my car. He use to tell me that I was a lucky one that my Cobalt had so few issues. He said it wasn't till the 07's did GM get the bugs out of the car. I heard many with electrical problems , even my cobalt had to have the radio changed due to a short. If you do research on the net for TSB's ( technical service bullitens) you'll read alot of issues GM knows about on the 05-06 Cobalts. Never buy a new design car the first 2 years of production.

Replying to: gerald41 (Mar 17, 2008 9:33 am) Thanks gerald . . .   yeah when i bought it . . it was totally an impulse buy . . it was actually a mistake but whatever. I havent had trouble with it at all really . . . i had to replace the MAP sensor and TPS sensor . .. but then found out those warnings were probably being set off by carbon build up in the throttle body . . but still i have 2 new parts on it lol.   other than that i really havent had any trouble with it . . just recently with the headlights . . and it has 108k miles so ive been pretty fortunate also . . . no other problems . .. the E brake light and highbeam display has come up once or twice but not for awhile.   yeah in hindsight i wouldnt have bought a new car at all . . . i LOVED My cavalier 1999 . . . i had NO trouble with it i sold it with 205k miles and got 3000 for it ha   well thanks again   Joseph
